Android: Ever go to a friend's house and try to join their Wi-Fi, only to be given an illegible password scribbled on a sheet of paper? Instabridge solves that problem: now, your friend can just invite you to join their network from their phone, and you'll instantly log in.

We've all been in this situation before, and Instabridge is an elegant solution. If you're connected to a network, you can invite any of your friends to join the network without having to locate and type in the password. If you decide you don't want them on your network anymore, you can remove them. Obviously, you should only do this with people you trust, lest you open your Wi-Fi to the entire world. Check out their security info for more on how Instabridge works.

The app only works on Android now, but the site hints at other platforms in the works, so keep an eye out. In the meantime, download it now at the link below to try it out.
